Precautions

US BOXED WARNINGS:
SUICIDALITY AND ANTIDEPRESSANT DRUGS:
-Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of this drug or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide.
-Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior.
-Families and caregivers should be advised of the need for close observation and communication with the prescriber.
-This drug is not approved for use in pediatric patients.

Safety and efficacy have not been established in patients younger than 18 years; this drug is not recommended for use in these patients.
